Urban heat island effect drives demand for thermally efficient building materials. TJYCT's color coated steel coils utilize infrared-reflective pigments that maintain 85% solar reflectance even after 10-year weathering tests. The galvalume (PPGL) substrate's 55% aluminum-zinc alloy composition outperforms traditional galvanized steel in coastal corrosion resistance. Architects appreciate our embossed finishes that conceal installation scratches while enabling rainwater harvesting system integration. With third-party verified EPDs, these coils help projects earn WELL and BREEAM credits.
